Wisconsin congressman and House Speaker Paul Ryan took a unifying tone in his address to his colleagues in the wake of Wednesday's shooting at a practice of lawmakers for the annual charity congressional baseball game, telling them that "an attack on one of us is an attack on all of us."

He praised the efforts of Capitol police officers and other law enforcement, calling them "our brothers and sisters in the line of fire."

Ryan received a standing ovation as lawmakers in both parties came to the House chamber as a show of unity.

Ryan said implored lawmakers in both parties "to resolve to come together to lift each other up and to show the country, show the world that we are one House, the people's House, united in our humanity."
